Past Tense of “sow”

The past tense of sow is sowed; the past participle is sown.

Why “sow” behaves this way

"Sow" (to plant seeds) comes from Old English "sawan," a Class VII strong verb, and is a distant cognate of Latin "serere" (to sow) and the English word "seed" itself, all tracing back to the same ancient Proto-Indo-European root for planting. Its participle "sown" preserves the old strong-verb "-en" ending pattern shared with "grown," "known," and "blown," even though the simple past "sowed" has taken on a regular-looking "-ed" ending rather than an ablaut vowel shift.

This mixed pattern — regular-looking simple past, but a distinctly strong-verb-style participle — puts "sow" in the same small category as "show/showed/shown" and "mow/mowed/mown," all of which are transitioning verbs caught midway between the fully strong Old English system and full modern regularization, having lost their vowel-changing past tense while keeping their old "-en" participle as a kind of grammatical fossil. Some of these verbs are actively regularizing even further today — "mown" is steadily losing ground to "mowed" even as a participle in everyday American usage — while "sown" has stayed comparatively stable, likely because of its strong association with the fixed biblical idiom that keeps the older form in constant circulation.

The common confusion

The overwhelming source of confusion with "sow" is its perfect homophone "sew" (to stitch fabric), a completely unrelated verb whose past forms are "sewed" and "sewn" — nearly identical in sound and spelling pattern to "sowed" and "sown," which means spellcheckers and even careful writers regularly swap the two in text about gardening versus textiles. A second confusion is with the unrelated noun "sow" (a female pig), spelled identically but pronounced differently (rhyming with "cow" rather than "go"), which occasionally trips up readers scanning quickly, since "the sow" could momentarily parse as an odd noun phrase built on the verb before the farming context clarifies which word — and which pronunciation — is meant.

How it's actually used

"Sow" is used both literally, for planting actual seed ("the farmer sowed the field in early spring"), and figuratively, for spreading something abstract like doubt, discord, or ideas ("the rumor sowed distrust among the team") — and this figurative extension, closely tied to the biblical parable of the sower, is now arguably more common in everyday writing than the literal agricultural sense. The figurative sense also pairs with a narrow but productive set of abstract nouns — discord, doubt, confusion, distrust, the seeds of an idea — almost always negative or destabilizing concepts, a semantic narrowing that doesn't apply to the literal agricultural sense, where you can sow anything from wheat to wildflowers.

Across the tense system

The participle "sown" appears constantly in the fixed idiom "reap what you sow" (technically "as you sow, so shall you reap") and in figurative perfect-tense constructions like "the seeds of doubt had already been sown," where the passive voice with "sown" is the standard, expected form; "sowed" would sound noticeably less natural in that same passive idiom. In ordinary agricultural writing, both the simple past and the perfect tense of "sow" appear constantly across a farming season's worth of records — "we sowed in April" (simple past, a single completed planting event) versus "we have sown these fields for generations" (perfect, describing an ongoing practice across years) — and the choice between the two carries real informational weight about whether the writer means one specific planting or a long-standing pattern.

Common real mistakes

By far the most common real error is confusing "sow/sowed/sown" with "sew/sewed/sewn" in writing, especially in fast typing where autocorrect doesn't catch the swap because both spellings are valid words. A second error is using "sowed" where the fixed idiomatic participle "sown" is expected, producing the noticeably less natural "the seeds of doubt were sowed" instead of the standard "were sown." A third error, common in agricultural or gardening writing translated from other languages, is treating "sow" as a regular verb throughout, producing "has sowed" consistently even in the idiomatic passive contexts where native speakers overwhelmingly expect "sown."

Examples

• The farmer sowed the fields before the rain came.
• Doubt had already been sown among the committee members.
• She sowed a row of carrots along the fence.
• The rumor sowed confusion throughout the office.
• They have sown these fields for three generations.
• He sowed the seeds of his own downfall with that decision.

Memory trick

Keep the vowel straight by pairing it with its meaning: "sow" seeds rhymes with "grow" plants — both are about agriculture and both take an "-n" participle ("grown," "sown"). If you're stitching fabric instead of planting seeds, you want the completely different verb "sew/sewed/sewn."
